How's the water?
He makes a valid point, whether he is "swimming" or not. By attacking the Catholic Church, you merely bite the hand that has given you the Scriptures in the first place. You implicitly trust their decisions on what is Scripture, while discarding the claims made by such Gnostic groups as those who follow the Da Vinci Code and other such nonsense. But WE say the latter is nonsense ONLY because we trust the Catholic Church's table of contents more than the Gnostics. Otherwise, why DO you reject the Gospel of Thomas???
NO ONE comes to the Scriptures without some paradigm or lense that we read it through. Men from different faith traditions read it differently, sometimes diametrically opposed. That's a simple fact.
